[Icecast] Reencode is it possible?

[alex]

Hi guys, i have a debian server running icecast 2.2.0 
Im interested in have a reencode process of the stream received from the oddcast DSP
I mean, if the oddcast is processing at 64 Kbps any way to receive the stream and reencode the stream to any other lower rate? The idea is to have the "bandwith" and "modem" options to the user without have to declare 2 encoders. Any comment or idea would be appreciate
Thanks in advance!
